How Vertical Wind Shear Affects Tropical Cyclone Intensity Change: An Overview

Filling the Gap of Wind Observations Inside Tropical Cyclones

“…But most importantly, they are among the most devastating of natural disasters causing widespread destruction due to strong wind and excessive amounts of rainfall when making landfall (Klotzbach et al, 2018).There is still no widespread consensus on the understanding and prediction of the genesis of TCs (Emanuel, 2003). Several studies have found that environmental vertical wind shear (usually defined between 200 and 850 hPa) is the main driver for the formation, intensification, and dissipation of TCs because of its capability of causing kinematic and thermodynamic asymmetries (Schenkel et al, 2020;Thatcher & Pu, 2011;Wadler et al, 2022) but intertwined complex multiscale processes generally govern TC intensity change (Judt & Chen, 2016). The understanding of the dynamical and thermodynamical structure, of the cloud microphysics and its evolution during TC's life cycle is still a matter of active research and is crucial to improve forecasts (R. Rogers et al, 2013).…”

Detection of stratospheric gravity waves induced by the total solar eclipse of July 2, 2019

“…Wind shear layers can produce gravity waves with the same average wind speed as the shear layer and with a propagation direction equal to the direction of the change in wind speed 2,14 . In this study, a shear level is characterized by an absolute value change in wind speed of 7.5 m/s or greater within a vertical range of 500 m or less 15 .…”
